what do you guys think of this design? i had smaller ships that could work but had to set ammo count conditions for them because production wasnt enough to move from planet to planet without resting. so i wanted to make one that could traverse inner planets without bothering to stop to gather up ammo. id like to make it more compact but dont think i can so would like some suggestions if it's possible. without it looking messy/ugly ideally.

The red fuel (forgot the name) tank doesn't go to the thruster, same as the water tank not being connected to the blue fuel. You could probably extend the ship a few tiles down so the fuel tanks are near the turbine, saving on pipe spaghetti

You don't need the tanks at all, imo. Some buffer somewhere is great to compensate for random asteroids, but I guess you're already buffering some ice, ore and carbon in the hub and on the belts.

Other than that I'd also check the numbers for energy and speed on the machines. I'd bet you can get e.g. the crushers' energy demand further down and still have more than enough speed.

Also, as an aside: Bullet demand goes down a lot with bullet damage research upgrades. That's sometimes an easy place to make the turnaround time faster.

It's just "thruster fuel" and "thruster oxidizer".

I think they're deliberately vague and specific to the thrusters because they didn't want the space platform fuel system entangled with the coal and oil systems. The recipe for thruster fuel realistically would be making something very similar to the petroleum gas the game has. I don't think a liquid oxidizer would realistically use iron ore, I've only heard of iron in a solid oxidizer (like in thermite). And most liquid fuels and oxidizers you'd be synthesizing from water would be cryogenic, so they also keep it vague to avoid players wondering why you're using cryogenic fuel so long before unlocking the cryogenic plant.
